LizardKing writes: The man who perfected the guitar amps used by so many famous musicians over the last fifty years has passed away. A former drummer, Jim Marshall initially became involved with guitar amplification as an importer of Fender equipment, until he eventually decided to branch out and make his own amps. The trademark Marshall sound evolved alongside the requirements of such luminaries as Pete Townshend and Eric Clapton. The Marshall stack has since become a ubiquitous symbol of live rock music in particular — so much so that some bands perform in front of veritable walls of Marshall branded speakers. In addition to his lead guitar amplifiers, Jim will also be remembered for his great bass amps (as used by Lemmy Kilmister in particular) and the much sought after Guv'nor distortion pedal.
